Hipparcos parallaxes for eta Boo and kappa2 Boo: two successes for asteroseismology
Timothy R. Bedding, Hans Kjeldsen, Joergen Christensen-Dalsgaard
Abstract
The release of the Hipparcos catalogue provides an opportunity to check results from asteroseismology. Here we show that Hipparcos parallaxes for two stars are in good agreement with oscillation results. For eta Boo, a probable detection of solar-like oscillations by Kjeldsen at al. (1994; astro-ph/9411016) gave a frequency splitting in good agreement with the Hipparcos luminosity. For kappa2 Boo, a delta Scuti variable, the Hipparcos parallax agrees well with the distance derived by Frandsen et al. (1995).
